Four pages, same shape as the stability ones: a task/mcp/rhino-command table,
the MCP route in python fences with the responses it actually returned, and the
command's options beside it. Every response and every claim on them was run
against the deployed 0.3.1 plugin; rotate_objects requires a pivot rather than
defaulting to the centre, which is what the page now says.

Four new images, and a demo file for the two that are not about stability:
guide_shapes.3dm holds one of each primitive create_objects makes, two of them
turned, on one layer in one material, rebuilt by --build-shapes out of the calls
page 03 shows. A scratch document would have been lighter, but Rhino cannot
close an untitled document through the plugin, so it has to be a file.

The root README sections these pages replace shrink to a pointer block.
